Cyclic Subgroups

Показать описание
I discuss how to generate a subgroup from a finite number of elements. I then define a cyclic subgroup and its generator. Finally, I define a cyclic group.

This is for an Abstract Algebra or Modern Algebra course.

Z6 can be generated by <1> and the inverse of one <5>.

to answer the question at the end of the video: generator "a" is not necessarily unique, because any value of "a" which is prime with respect to the mod # (in this case prime with respect to 6) could be the generator, in this case, that would be 1 & 5 which are both the generator here.
